aToDCount
type: NamedIndividual
type: SimpleUnit
symbol: #
name: aToDCount
description: An analog to digital count is a number produced by an analog-to-digital converter to measure a physical quantity. The measurement action counts the time for the measurement transducer to reach equilibrium. A count represents a quantity kind that depends upon the analog process that is being measured. For this reason, the association between count and quantity kind should ideally not be fully specified in this ontology, but should wait until the time of describing a particular device. However, that specification may require additional syntax in a schema. The current strategy in this ontology is to leave the specification of quantity kind to the point of description of a device, and to expect the additional syntax in the schema that uses this concept. The alternative is to define a subclass of AToDCount for each quantity kind. The delayed specification of quantity kind may provide a model to simplify the definition of other units. Typically, a count will be the basis for a conversion-based unit that converts the count into a physical quantity.
